Virginia Grid Utilization Law Sparks National Policy Shift
Virginia enacted the first U.S. law requiring utilities to measure grid usage and file efficiency plans by mid-October 2026.
Virginia has become the first state to require its major electric utilities to quantify and improve how much of the power grid is used. Dominion Energy and Appalachian Power must submit their grid utilization plans and efficiency assessments to state regulators by October 15, 2026. The pioneering law is triggering a wave of similar legislative interest across the country, signaling a potential shift in how the U.S. power grid is planned and optimized for cost and capacity.
Utilize Coalition’s role in shaping the policy
The policy was endorsed by the Utilize Coalition, a nonprofit advocacy group whose members include Google and Tesla. Founded by Ian Magruder, the coalition recently released a detailed proposal for measuring grid utilization. The paper, Beyond Peak: Defining, Measuring, and Optimizing Grid Utilization, proposes a common framework where utilization is defined as the share of deliverable energy that is actually delivered over a given period. Unlike peak measurements, this captures how infrastructure delivers value across time.
Magruder argues that current metrics like load factor are insufficient. He sees grid utilization as a diagnostic tool to inform more cost-effective planning. It can identify pockets of unused capacity where technologies like batteries add value, or highlight areas of high constraint where new infrastructure is needed. A recent study by the Brattle Group suggested that using the grid more efficiently could save utility customers over $100 billion in the next decade.
Pier LaFarge, who heads the coalition’s advisory board, links the timing to technological innovation. For decades, grid was built for peak demand, leaving half of capacity unused most days due to a lack of technology. "I really think utilization has a chance to be the key that unlocks a lot of progress on deploying distributed capacity," LaFarge said. He believes maximizing throughput is now possible and can unlock more delivered energy while improving affordability.
The coalition emphasizes its framework should add to, not replace, existing grid planning factors like reliability and cost.
National ripple effect and broader context
Virginia's process is being closely watched. Several states have shown emerging legislative or regulatory interest, including Colorado, Maryland, Michigan, Minnesota, Montana, New Jersey, North Carolina, and Ohio. The momentum is closely linked to the push for flexible data centers and broader affordability concerns. An independent Brattle Group analysis found better grid utilization could reduce consumer electricity bills by more than $100 billion over the next decade.
The interest follows a Duke University study from nearly two years ago, which found that a small amount of data center flexibility could unlock 100 gigawatts of grid capacity. Since then, the market has been flooded with ideas for squeezing more from existing infrastructure.
Challenges and criticisms in implementation
The push for grid utilization has drawn criticism centered on the difficulty of creating consistent metrics. Experts warn the lack of measurement options risks undercutting the Virginia policy's effectiveness. Power market analyst Oliver Kerr argued that any metric must account for variables like temperature, wind speed, generation mix, and infrastructure age. Comparing utilization across utilities will be hard due to these regional factors.
Another challenge is the utility business model. Utilities remain financially incentivized to build new wires and generation, as that is how they earn a profit. However, Pier LaFarge isn't convinced this would prevent utilization from lowering rates. He explained that when demand grows, infrastructure costs are spread across more sales, improving economics. Load growth, he suggested, fixes many issues within the current system.
The upcoming utility filings will be a first test. They must include both the proposed utilization metrics and assessments of how efficiently existing grid infrastructure is being used.
